You can't just take off the charge time of the oblivion guns and call this a "fix" for the Aeon destroyer/T2 PD/Battleship. First of all, it looks ridiculous, the gun still charges, but only after it fires. Second, that charge time was there for a good balance reason.
Either figure out how to fix it properly by making the weapons aim during charging, or just admit you broke something to give Aeon an unfair advantage.
